' i 4'Claims. or. 206 -47) This invention. relates to a spool structure,wherein means is provided for supporting and shielding a bobbin 'endportion of a spool showing a bobbin mounted therein,

and a label clement-for retaining the bobbin against displacement fromthesp'ool.

Fig.- 2Iis a'partial end view of the'structure shown in Fig. l, withpart of the construction broken away and in section; and a Figs;3Iand4'are viewsfsimilar to Fig. l, on a smaller scale, showing modifiedforms of construction.

This application constitutes a COl'ltlIlllZltlOl'l-lll-Pflli of thestructure disclosed in my prior application filed June 22,

1953, hearing Serial Number 363,309, now abandoned.

Myprescnh-invention deals with spool structures having spun-over;or'forrned, label engaging rims for securing labels at spool ends and,more particularly, with the utilization of structures of this type andkind, wherein the label element is further used in retaining a bobbinagainst displacement-from the spool end. As the bobbin is disposed atone end portion only of the spool, the present disclosure will dealsolely with one end of the spool.

In illustrating one adaptation and use of my invention,

I have shown Figs. 1 and 2 a moulded spool structure,

comprisingan inner tube or cylinder 10, an outer tube or cylinderllljoining the inner cylinder in circumferen.

tially spaced: radial ribs or wall portions 12, of the general contournoted in Fig. 2 of the drawing. The end of the spool has an outwardlyflared rim 13 which defines, around the cylinder 11, an annular recess14'for reception of the thread, asdiagrammatically illustrated at 15.-The outer surface of the rim is preferably provided with a series ofcircumferentially spaced ribs.16 forming corresponding recesses, asnoted at 17 in Fig. 1 of the drawing.

. In the construction shown, the ribs 12 are disposed in wide'spaccdrelation to the outer end portion 18 of the cylinder 11 to form a largeannular chamber 19 outwardly of the ribs 12.

Extending into the chamber 19, the ribs 12 have other United StatesPatent- O l cc Y Patented Dec. 2, 1958 label element 24, is preferablymade of a transparent or translucent cellophane and this label is heldin position an outwardly extended. portion of the end 18 of the cylin-'der 11,.to facilitate insertion of the bobbin 21 intothe chamber 19 andarrangement of the label 24 in position on the surfaces 22 and 23, afterwhich, the flange or rim 25 is then formed.

In the use of the combined spool bobbin structure shown in Figs. 1 and 2of the drawing, the label 24can be broken through the bore 26 of thebobbin 21 and, then, torn from the spool end to free the bobbin forremoval from the chamber 19.

'1 n Fig. 3 of the drawing, 1 have shown a modified form of.construction and, in this figure, a moulded spool is diagrammaticallyshown at 27, the spool having-a label retaining flange or rim 28,similar to the flange or rim In this construction, a bobbin 29,generally similar to the bobbin 21, is mounted upon the end surface 'ofthe. spool 27 and .a label element, inthe form of a shell or casing 31,is employed, the element 31 having a cup-- ciently strong to support thebobbin against shifting move-' ment on thespool end.

The modification of Fig. 4 'dilfersfrom that ofFig. 3

- .only in the construction of the spool 34. The latter, ex-

circum'ferentially spaced ribs 20, generally T-shaped in cross-sectionalform, as will appear from a consideration of Fig. 2 of the drawing. Theribs 20 reduce the size of the chamber 19 and form positioning guidesfor a bobbin 21 so that the bobbin 21 is centralized on the spool end,in the manner clearly illustrated in Fig. 1 of the drawing.

It will appear that th'elouter surface 22 of the bobbin I is inalinement with outer ends 23 of the ribs 20, thus producing alined labelsupporting surfaces 22, 23, upon which a label disc '24.isadapted torest. The label, or

cept for flange 28', is described in copending application Serial'Number423,457, filed April 15, 1954, and for convenience, a brief descriptionof the spool may be given here. it comprises a one-piece, integrallyformed, all

plastic thread spool comprising a barrel 35 having a pair of flanged endportions, one of which is shown at 36, of such size as to provide aso-called deep .grooved spool capable of holding a substantial amount ofthread.= The barrel, when viewed in cross-section, comprises an annularwall of substantial thickness. Each flanged end portion comprises aplurality of concentric annular grooves bore 44. The innermost groove 43extends into the annular wall of the barrel for a distance (not shown)less v than half the length of the barrel, andthe-remaining groovesterminate as shown. Each adjacent pair of .annular walls is connected toeach other by a plurality of circumferentially spaced, radially disposedribs, one of which, for example, is shown at 45, each rib being locatedin a groove and being coextensive in length with the depth of thegroove. The free ends of the walls and ribs lie" in the end face of thespool. f

The bobbin and bobbin retaining structures of Fig. 4.

are like that of Fig. 3 and are identified by similar but I primedreference numerals. With all modifications, the label element,in'addition to retaining the bobbin against accidental displacement fromthe spool, also provides a protective covering to'prevent dust and dirtfrom collecting upon the bobbin. In each case, too, the spool has abobbin in association with it, and the bobbin carries thread correctlychosen with respect to-the thread on the spool. The purchaser thus I Itwill be appreciated thatthe particular spools shown n the drawings areillustrative. That of Figs. 1-2 is an lntegrally formed, all-plastic,light weight spool of pleasing over-all appearance. Thecircumferentially extending ribs 16 and recesses 17 on the periphery ofthe end portion of the spool provide a decorative effect and increasethe attractiveness of the spooll The circumferentially spaced ribs 20may be omitted in spools of smaller size, that in spools whose tube orbarrel 11 has approximately the same diameter as the bobbin so as toenable the bobbin to fit snugly in the compartment in the absence of theribs. Figs. l-2 illustrates the use of a compartment in an end portionof the spool for receiving the bobbin, while the spools of Figs. 3 and 4show how the bobbin ma be disposed outwardly of the end face of thespool. Fig. 4

' further shows that spools too small to be provided wit a compartmentmay yet be enabled to carry a bobbin. if desired, the spools ofFigs. 3and 4 may be provided with an extension engageable in the bore of thebobbin, as

set forth in said copending application.

As illustrated, and as will be understood, the spool construction isvariable. In each case, however, a retaining element for the bobbin isprovided which extendsacross the end of the spool and across the outerend face of the bobbin. Peripheral portions of the end of the spool aremovable or deformable so that they overlap or extend over ontoperipheral portions of the retaining element to secure the element tothe spool end. The spool may be entirely or partially made of plasticand may be formed integrally or from two ormore pieces. A spoolpartially made of Dlasticcomprises one whose rims or peripheral flangedportions are of plastic. and in such case movable or deformableperipheral portions may be formed on such plastic portions if the latterare not adapted to be. moved.

In order to moveor fold the flanges 25, 28, and 2% s over ontoperipheral portions of the retaining element. it is preferred to heatthe flanges and tofold them over by means ofa suitable forming tool suchas is described in copending applications Serial Number 442,137, filedJuly 8, 1954, and Serial Number 442,138, filed July 8,. 1954.

Theretaining elements 24, 31, and 31 may be of paper, foil, cardboard,plastic, and the like. They may-have 'printed information on them andthus serve as labels as well as retaining'elements, and/or they may betransparent to expose .the bobbin to view, in which case they arepreferably made of a material like cellophane or sheet plastic. Ifdesired, bobbins may be supported at both ends of the spool. 1
